Groundwater in Morris County contains manganese, iron, radon, uranium, lead, chloride, and PFOA and PFOS compounds at levels that exceed EPA health standards. These contaminants require attention from well owners in this county.
The crystalline rock beneath Morris County naturally releases manganese and iron as water moves through it over time. Radon and uranium come from the rock itself as it slowly breaks down. Chloride and PFOA enter groundwater from road salt, de-icing products, and industrial sources in this developed area. Lead leaches from pipes and fixtures in older systems.
Groundwater in Morris County shows moderate iron content from the minerals in the bedrock. The crystalline rock here contains iron-bearing minerals that dissolve slowly into water passing through fractures and pores. This iron concentration is common across wells throughout the county, varying from well to well depending on depth and local rock type.
Wells in Morris County commonly contain chloride, iron, manganese, PFOS, lead, radon, and uranium at levels above EPA health standards. Exposure to these contaminants can damage your kidneys and liver, affect your blood pressure, harm your bones, and increase cancer risk. Lead is especially dangerous for children and can affect brain development. Radon and uranium both carry radiation risks, while PFOS and PFOA are forever chemicals that build up in your body over time.
County well water with moderate iron levels can stain your clothes, dishes, and plumbing fixtures with orange or brown marks. Iron can also give water a metallic taste. While the mineral levels in this county are generally low for hardness, any iron present will require attention to keep your home and laundry clean.
We recommend a comprehensive water test to find out exactly what is in your well, since every well is different and yours could have higher or lower levels than the county average. Testing is the only way to know what needs treatment. A full metals and minerals panel typically costs between two hundred and four hundred dollars. Water treatment options like reverse osmosis, ion exchange, or activated carbon filters can address multiple contaminants depending on what testing shows.
